IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 30,079, dated September18, 1860.

To all whom it may concern:

Be it known that I, DANIEL MOORE, of Brooklyn, in the county of Kingsand State of New York, have invented, made, and applied to use. certainnew and useful Improvements in Revolving-Breech Fire-Arms; and I dohereby declare that the following is a full, clear, and exact'description of the construction and operation of the same, referencebeing had to the annexed drawings, making part of this specification,wherein- Figure 1 is a side elevation ofmy improved arm, and Fig 2 is anend view with the barrel and cylinder removed and the center-pin onwhich the cylinder revolves in section.

Similar letters ret'er to the same parts.

My said invention relates to a means for attaching the stock, barrel,and cylinder, so that said cylinder can be swung aside from the stockfor the purpose of loading or removing the charge from the piece; butwhen in position for firing said parts are,held firmly,

together. My revolving-breech fire arm is adapted to volcaniccartridges, in which a metallic capsule contains the powder and receivesthe ball, a hollow flanged ring being provided for the fulininatingmaterial around the base of the cartridge.

In the drawings, ais the stock, of any usual size or shape. I) is thebarrel, either rifled or plain. c is the cylinder of chambers or revolwing breeches. dis the metallic breech-piece behind the chambers, and eis a connection therefrom beneath the chambers. 0 to the bracket f onthe lower side of the barrel b. These parts 0 and fare attached to eachother by a gudgeon, 1, projecting from the former and passing through ahole in the bracket f, and 2 is a nut securing the barrel and bracket tothe stock.

The center-pin 3, on which the chambers c revolve, is formed as shown bydotted lines in Fig. 1. The forward end of this pin enters the part fbelow the barrel, where it is secured in place by the screw 4 or anycompetent means, and a shoulder on this pin serves to prevent thechambers disconnecting or sliding off the pin when the barrel isdisconnected from the stock. On the rear end of the pin 3 is a collar bywhich the stock and barrel are connected. For this purpose I provide arecess in the breech-piece d, as seen at g in Fig. 2. This recess isformed large enough at one end to pass the said collar, and is undercutor grooved, so that when the barrel and stock are in proper line thesaid recess contains the pin and the collar on the end thereof in thespace formed behind for the same, as seen in Fig. 2. barrel and chambersare turned aside on the gudgeon 1 to the position shown by red lines inFig. 2 that some of the chambers are clear of the metallic breech-pieced and are open from end to end, so that the said chambers can be clearedof the metallic cartridge-case and a new cartridge. inserted, and thecylinder can be revolve-d while in this position so as to give access tothe respective chambers. When turnedvback to its place the collar on theend of the pin 3 makes a firm connection between said pin and thebreech-piece d.

It will now be evident that when the To prevent the cylinder and barrelswing ing aside when in use, 1 provide the latch i, which, springinginto a notch in the collar of said pin 3, retains the parts in positionfor firing. The end of this latch, projecting from the side of themetallic breech-piece, allows for its being moved by the thumb or fingerwhen the breeches are to be swung aside.

k is the hammer for exploding the cartridge, the same being actuated bya suitable mainspring. l is the trigger; m, the pawl for revolving thecylinder of breeches, and nis the stop for holding the respectivechambers in line with the barrel. These various parts k, l, m, and a donot form any part of my present invention. They may therefore beconstructed and operate in any well-known manner, and as is usual inthis character of the The center-pin 3 and its collar at the back end,retained within the recess 9, combined with the cylinder 0 and barrel b,swinging on the gudgeon 1, in the manner and for the purposes set forth,and in combination with said center-pin 3, moving as aforesaid, thelatch i, to retain the parts in place while the arm is being discharged,as specified.

In witness whereof I have hereunto set my signature this 17th day ofJuly, 1860.

I DANL. MOORE.
